What type of transducer is used for OB/GYN and abdomen exams?

The curved transducer is commonly used for OB/GYN and abdomen exams due to its design, which allows for a wider field of view and better depth penetration. This curved array shape is well-suited for visualizing larger structures, which is essential when evaluating the abdomen or during obstetric examinations. The curvature enables the transducer to effectively capture large areas in a single sweep, which is particularly beneficial for monitoring the development of a fetus or assessing organ size and pathology within the abdominal cavity.

The curved transducer also typically operates at lower frequencies than linear transducers, providing improved penetration depth, which is vital for obtaining clear images in the abdomen and pelvis where structures can be situated deeper under layers of tissue. This balance of frequency and design makes the curved transducer a preferred choice in these clinical applications.

In comparison, while linear transducers offer excellent resolution over smaller, superficial structures, they are not as effective for deeper imaging. Phased array transducers are typically used for specific applications such as cardiac imaging rather than general OB/GYN or abdomen evaluations. Endocavity transducers, designed for specific internal examinations, do not provide the broader view needed for abdominal or gynecological assessments.
